Anamorphic Prism Pair, good for 635nm?

Hello, here's a anamorphic prism pair on ebay, I believe these were taken out of a IR laser but the seller is listing them as a beam expander prism pair for 635nm. Anyone here ever use one of these IR prism sets at 635nm?

The seller is tcle2745 in La Valle, Wisconsin, anyone here know this seller?

IR optics will work just fine for red, just possibly have slightly higher losses. It depends on the coatings.

How about one of these designed for 808nm being used at 1064nm? Any idea if the losses might be worse in that direction for a longer wavelength?

If they're like those prism pairs from the B+W DPSS blues, they seemed pretty lossy, especially going through two of them.

You could also check out the prism pair from LaserShowParts, or the equivalent from eBay like these; they're supposedly coated for broadband. The overall price is about the same.

Thanks, appreciate the link, hadn't known about them before.

I have a larger pair of anamorphic lenses here and finding that shooting a less than fully collumated beam into them doesn't work out to make a nice round spot when putting a pcx lens on the other side of the prisms to collimate it, doing so makes a very oblong output, completely reversing what I was trying to use the prisms for, making it worse than it was to begin with

Edit: Of course, if I collimate the beam first prior to the prisms, it works correctly. I was hoping I could shoot a uncollimated beam through it, if close enough to the diode, which I can, but then when trying to collimate the beam after it leaves the prisms it won't do so, all distorted.
